HAND TACKINGOR NAILING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 287,375, dated October23, 1883. Application filed May 7, 1883. (No model.)

To aZZ whom it may concern.:

Be it known that I, LOUIS GODDU, of Vinchester, county of Middlesex,State of Massachusetts, have invented an Improvement in Hand Tacking orNailing Apparatus, of which the following description, in connectionwith the accompanying drawings, is aspecication, like letters on thedrawings representing like parts.

My invention relates to an apparatus for driving tacks or nails inleather or other material, and is herein shown as adapted to driveso-called string-nails. l

In my improved apparatus the reel which holds the string-nails is placedona spindle or pin of a bracket attached to or forming part of a tube,upon the lower end of which is secured the nose through which the' nailis driven by the driver. This nose is left open at one side, or isslotted for the reception of a driver,

represented as a lever pivoted upon the hand- Y* piece, which, chamberedcentrally, is adapted to slide 011 the tube referred to. The handpieceis normally kept elevated by a spring, the lower end of which rests on ashoulder of the tube, while the upper end of the spring acts against thehand-piece. The driver is also adapted to act as a cutter to sever thedriven nail. The operator grasping the handpiece strikes the noseagainst the thing into which the nail is to be driven; but the handpiececontinues to descend after the nose is arrested, during which time thedriver acts upon the head of the nail, and drives the same and cuts itoff, as will be described.

Figure l represents inside elevation and partial section an apparatusembodying my invention; Fig. 2, a section on the dotted line Fig. 1;Fig. 3, a view of the driver detached; and Fig. 4, a view of the noseremoved from the tube, and a section thereof.

The spool or reel A carrying the string-nails a, is placed and turns onastud, B, of a bracket, C, attached to the upper end of the tube D, thelatter having attached to it at its lower vend the nose D2, having anopen channel, d,

at one side leading into it. The string-nails are passed over thetake-up spring a3, and

down through the tube and into the nose, as

shown in Fig. 1. The tube has a shoulder, 2,

to receive against it the spiral spring E, and

-trally and provided with a driver, G, (shown as a lever pivoted thereonat g,) and provided at its lower end with a cutting-projection, 3, whichco-operates with a beveled surface, 6, (shown inheavy black, Fig. 4,) atthe lower end of a steel-cutter member, m, held between the jaws of thenose by the screw n, the projection 3 commencing to cut the nail at theupper edge of the said beveled surface, and completing the cut beforereaching the lower end thereof, after which the nail is completelydriven. The driver-lever G has awedge-shaped projection, h, (shown asforming part of an arm, 712,) connected with the said lever, the saidarm and projection being made adjustable by means of an adjustingdevice, 7L. (Shown as a screw.) The tube Dghasan inclined projection,10, against which the incline of the projection 7L strikes as thehand-piece and the driver-lever are forced downward, the said projectionand incline being so located with relation to each other and the nosethat the cutter 3 of the driver-lever in engagement with the head of thenail being driven is made to enter or cut into the string nail as thecutter 3 comes opposite the upper edge of the inclined part 6 of themember m, and to fully sever the said nail while moving from the top tothe bottom of the said inclined surface 6, as described. The upper end.of a spring, 8, (shown in dotted lines,) acts against the driver-lever Gabove its pivot g', and normally causes the cutter 3 to remain incontact with the string-nails, and the lower end of the said spring actsas a detent to prevent retrograde movement of the string-nails, asusual. Adjustment of the projection h determines the extent of themovement of the driver about its pivot when severing a nail. The normalcondition of the apparatus is, as in Fig. l, with the vhand-pieceelevated and the end of the driver-lever in contact with the head of thenail neXt to the driver.

The operator, to drive a nail into the sole or other part of aboot orshoe or other article, will grasp the hand-piece and strike the nose l)2down upon the spot where the nail is to be driven. When the nose strikesthe material its lmotion is checked, but the hand-piece continues todescend until the shoulder 4 strikes the nose, and during` this movementthe end 2. The hand-piece, the driver pivoted there# on, and the springE within the said handpiece, combined with the tube and its nose to restupon the material, substantially as 4described.

3. The tube D, its nose and projection and cutter-member m, combinedwith the handpiece, the driver pivoted on the said handpiece andprovided with a projection to cooperate with the projection on the saidtube,

and with a cutter, 3, to operate substantially as described. v

4. The tube provided with the nose and cutting member, and with theprojection 10, conibined with the hand-piece, and the driver-1everhaving the cutter 3 and the adjustable projection 7L, to operatesubstantially as described. In testimony whereof vI have signed my nameto this specication in the presence'of two subscribing` witnesses.

LOUIS GODDU.
